66kV Substation Project Feasibility Study And Preliminary Design

In this paper, a town on the natural conditions and economic development wereanalyzed, and electricity load growth is predicted, raise the current can not meet the theactual demand for electricity problems. Since the original substation equipment than theold part of the equipment can not be upgraded, therefore, a new66kV substation isnecessary.In accordance with the actual situation local power system and the engineering needs,determine the design principles and scope of design, from the conservation of farmlandand facilitate network planning perspective, plans new substation site. Accordance withthe design specifications of the original station site area basically meet the new electricalsubstation layout requirements. the path determined using the original line access to66kVsystem solutions. Through electrical calculations. Determine the electrical parameters andthe main connection forms. Predict the development of local loads, select the maintransformer capacity and wire cross-sectional area. Analysis of load composition,determining reactive power compensation capacity and main transformer neutralgrounding. Under way and dispatching automation system protection status, determinerelay configuration and scheduling communications solutions.Secondly, the combination of local hydrological and meteorological conditions,determine substation construction building programs.Finally, in accordance with the overall construction plan, preliminary design,proposed the building of conclusions.Meanwhile, energy saving, environmental protection, disaster analysis of measures toensure compliance with energy saving, environmental protection, disaster conditions.
